NSWO bill snaps; HY bird. Recorded inside BBBO lab while being banded by Erin L.
观察细节
not exceptionally high for this area, especially given the effort and time of year. banded at BBBO and so accurate as far as no chance for over-counting individuals. I'm not sure what the eBird protocol is for banding stations, but I imagine these data (giving a decent snapshot of migrant NSWO numbers in the immediate vicinity) is as good, if not more useful, than any. In addition to the 6 birds banded during this period were the following NSWO vocalizations heard: wail/aggression call, fall & winter vocalizations/ksew/barks. These additional vocalizations were likely from individuals which were either A. released post-processing or B. yet to have been, but eventually were, netted and so the count of 6 is likely as accurate as it can be.
